Zduriencik has been at the helm in Seattle since 2009, but his most recent deal was set to expire after this season. He declined to comment on his contract situation, telling Geoff Baker of the Seattle Times that team chairman Howard Lincoln or president Chuck Armstrong "would be the ones to announce something like that, if there's any truth to it." Armstrong also refused comment, Baker tweets, citing club policy. While we still do not have official acknowledgement, however, all signs point to a return for Jack Z.

While the M's have yet to post a winning season under Zduriencik since his first year in charge, and have scuffled for most of 2013, there have been signs of promise. Seattle's young position players — including three of the first players Zduriencik drafted (Dustin Ackley, Nick Franklin, and Kyle Seager) — have taken on prominent roles across the diamond, with varying degrees of success. Perhaps most encouraging, first baseman Justin Smoak, who headlined the haul Zduriencik returned for ace Cliff Lee back in 2010, has posted by far his best big league season. With the club's top pitching prospects knocking on the door in the upper minors, it appears that Zduriencik will have at least one more chance to turn out a winner.

Jack Zduriencik is still the right person to serve as the Mariners' GM, Jerry Brewer of the Seattle Times contends. Brewer points to a strong farm system (which includes the likes of Taijuan Walker, Mike Zunino, Danny Hultzen and James Paxton) as evidence that Zduriencik's plan is working. The Mariners have only had one winning season since Zduriencik was hired, however. "I can't say that I'm happy, can't say that I'm satisfied at all," Zduriencik said. "Because, at the end, it's about the finished product at the big-league level and all of these kids becoming what you want them to become." The M's finished 75-87 in 2012. Here are more notes from around the majors.

Napoli will be an impact hitter for the Red Sox in 2013 because he will no longer catch, Michael Silverman argues, also in the Boston Herald. "Now there’s more of a flow to everything," Napoli says. "It’s a tough position — catching and good-hitting catchers are tough to find. It’s just a grind — a grind that I do miss, but I don’t miss." Napoli caught in 72 games for the Rangers last year, but the Red Sox signed him to an incentive-laden one-year deal for 2013 with the plan that he would play first base, where, Silverman writes, he has looked "nimble and sure-handed" this spring.

The Dodgers "do not appear close" to trading one of their starting pitchers, writes Bill Shaikin of the Los Angeles Times. Since the Dodgers cannot ship Aaron Harang, Chris Capuano or Ted Lilly to the minors without those players' consent, teams may simply wait for the Dodgers, who don't have roster space for all their starting pitching, to become more desperate. The Orioles, Brewers and Pirates "have expressed interest" in the Dodgers' surplus arms, Shaikin notes, but the Rangers are not a likely trade partner.

The Mariners successfully prevented their opponents from scoring in 2012 — just two American League clubs allowed fewer runs. However, no AL team had more trouble generating offense than Seattle, which finished last in the league in scoring. Will the Mariners swap arms for bats, or will moving the fences in at Safeco Field be enough? GM Jack Zduriencik checked in with MLBTR at the 2012 GM Meetings at Indian Wells, California. Here are some highlights…

The Mariners have lots of young pitching, and they’re not going to rule out the possibility of trading it to strengthen other areas of the team. “You have to keep your options open,” Zduriencik said. “At this stage people are feeling each other out, people are lining their ducks up in a row. All 30 clubs are doing this and everybody has their Christmas list if you will.”

Zduriencik will consider trades and free agency as the Mariners search for offense. “You never know what’s going to be out there,” the GM said.

Early on in the offseason, there’s “an awareness” from free agents that the Mariners will be moving the fences in at Safeco Field in 2013. “It certainly becomes a conversation piece and hopefully it helps us.”

Mariners GM Jack Zduriencik says the Mariners are looking to acquire starting pitching depth, relief help, a backup shortstop and offense this offseason. Here are more of Zduriencik's updates on the Mariners from an afternoon conference call with reporters:

Zduriencik declined to comment on negotiations with specific free agents, including Prince Fielder(the Mariners are interested). The GM said the Mariners may turn to the free agent market for offense if they can match up with available players in terms of years and dollars.

"We will explore several options, even trades," he said. "But there aren't any promises on these things. You don't know where you're going to end up at."

The Mariners are looking forward to bounce-back years from Franklin Gutierrez and others who struggled with injuries in 2011.

"When you look at some arms that are pretty close and you look at some arms we have in the Major Leagues, we have some pretty strong assets here," he said.

The Mariners will again be a young team in 2012, but the front office will likely add some veterans to complement the existing group.

Zduriencik expects restrictions on spending in Latin America to have more of an effect after this year. He likes the options on the international free agent market, but isn't promising to sign any of them.

"There are some nice pieces out there," he said. "But they're not going to come inexpensively."

SATURDAY: Zduriencik's new deal is for two years, tweets Jon Heyman of SI.

WEDNESDAY: The Mariners announced a multiyear extension for GM Jack Zduriencik. Despite the team's place at the bottom of the American League West standings, president & CEO Chuck Armstrong says the club is headed in the right direction for long-term success.

“Jack arrived in Seattle with a clear plan, and he has not deviated from that plan,” Armstrong said in a team press release. “Jack wanted to increase the talent base in our organization through scouting and player development. That is exactly what he has done.”

Zduriencik, whose contract was set to expire after 2011, said today that he intends "to continue to acquire talent at all levels of [the] organization" as the Mariners look to improve.

The Mariners won 85 games in 2009, the club's first season under Zduriencik. However, they lost 101 games last year and are now 57-77, last in the AL West.

Zduriencik became the first non-GM to win Baseball America's executive of the year award in 2007, when he was Milwaukee's scouting director. He has spent 28 years working for MLB organizations, including nine with the Brewers (1999-2008).

The Dodgers fired hitting coach Jeff Pentland and named Dave Hansen interim coach through season's end, the team announced on Twitter. Not that it's entirely Pentland's fault, but the Dodgers are 15th in the NL with 3.63 runs scored per game.

Padres closer Heath Bell appeared on ESPN's Doug Gottlieb show yesterday. He thinks his top three suitors are the Rangers, Phillies, and Cardinals, and believes he'd probably close only for the Cards. SI's Jon Heyman says the Padres have considered taking draft picks for Bell after the season or re-signing him if they don't get what they want this month. Heyman lists the Phillies, Reds, Rangers, Cardinals, Pirates, Angels, (and the White Sox and Yankees to a lesser degree) as suitors. By the way, check out our Bell archive over at CloserNews for fantasy advice.

Trade candidate Erik Bedard will likely have his return delayed until after the Mariners' series with Boston at Fenway this weekend, reports Geoff Baker of the Seattle Times. He might have one start to display his health prior to the July deadline.

Mariners GM Jack Zduriencik told SI's Jon Heyman he hasn't heard nor has he asked about his situation. Zduriencik's contract is up after this season.

Dodgers GM Ned Colletti explained to Dylan Hernandez of the L.A. Times that "it's not that cut and dry" to label his club buyers or sellers. Though the team has no chance in 2011, Colletti may be willing to acquire players who are controlled beyond this year.

On this date in 1998, former New York Highlander and St. Louis Brown Red Hoff passed away. At 107 years, four months, and nine days old, the left-handed pitcher had the longest life span of any player in Major League history, out-living his closest competition by more than five years. He pitched to a 2.49 ERA in 83 innings from 1911-1915, but never played after serving in World War I.

Ed Price of AOL FanHouse has a list of salary figures exchanged by players and their teams at today's arbitration filing deadline.

Ed Price of AOL FanHouse (via Twitter) spoke to a scout who saw Ben Sheets' throwing session today. "He threw very well. He threw easy," said the scout, who guessed that Mets, Cubs, and Rangers were the leaders for his services.

The Rays and B.J. Upton did not reach a deal today, and his agent indicated that the two sides will head to an arbitration hearing according to Marc Topkin of The St. Petersburg Times (via Twitter). He later tweets that they may be just $300K apart.

Jon Paul Morosi of FoxSports.com reports that the Cubs, Cardinals, and Dodgers are monitoring free agent lefty Mark Mulder. Late last week we learned that the Brewers were going to wait before deciding whether or not to offer Mulder a deal.
